Cancel a batch - Amazon Mechanical Turk

Amazon Mechanical Turk will permanently close on September 30, 2026. For Workers and Requesters currently using the service, visit our Amazon Mechanical Turk help page to learn how you can prepare for this closure.

Cancel a batch

If the batch you published isn't working the way you'd like, you can cancel it.

To cancel a batch

  1. On the Mechanical Turk Requester website at https://requester.mturk.com/, choose the Manage tab and then choose Results.

  2. Under Manage Batches, choose the arrow next to Batches in progress.

  3. Choose Cancel on the batch you want to delete.

  4. In the Cancel Batch dialog box, choose Yes.

It can take several minutes to cancel a batch. All Workers who accepted assignments before you deleted the batch can continue working on them. The batch won't be completely deleted until all assignments accepted by Workers have been returned, submitted, or abandoned.
